Questions and Correct Answers
base placement - Answer -✔✔Refers to the position of the rod in relation to its base
section; base is determined by the angle at which the hair is wrapped.
on base placement - Answer -✔✔Base control in which the hair is wrapped at a 45-
degree angle beyond perpendicular to its base section, and the rod is positioned on its
base. (greater volume)
half of base placement - Answer -✔✔hair is wrapped at a 90° perpendicular to its base
section rod is positioned half off its base section minimize stress and tension on hair
off-base placement - Answer -✔✔Base control in which the hair is wrapped at 45
degrees below the center of the base section, so the rod is positioned completely off its
base. (least volume)
Base direction - Answer -✔✔Angle at which the rod is positioned on the head
(horizontally, vertically, or diagonally); also, the directional pattern in which the hair is
wrapped.
base sections - Answer -✔✔Subsections of panels into which hair is divided for perm
wrapping; one rod is normally placed on each base section.
Base - Answer -✔✔foundation of curl . area closest to the scalp panel of hair which
roller is placed
stem - Answer -✔✔between the base and first arch (turn) gives curl definition and
mobility hair between scalp and the first turn of the roller
circle - Answer -✔✔forms a complete circle the wave size of a curl will determine
width/wave and strength
No stem curl - Answer -✔✔(Betty boo) on base of curly , tight firm long lasting minimum
mobility
Half stem curl - Answer -✔✔Curl placed half off the base; permits medium movement
and gives good control to the hair.
full stem movement - Answer -✔✔greatest mobility placed completely of base near
scalp will be flat and almost straight give hair strong define direction
, Exothermic - Answer -✔✔produces heat (alkaline) heats up waving solution
Endothermic - Answer -✔✔Absorbs/require heat (acid) use hooded dryer (less
damaging)
ammonia-free waves - Answer -✔✔Perms that use an ingredient that does not
evaporate as readily as ammonia, so there is very little odor associated with their use.
thio-free waves - Answer -✔✔Perm that uses an ingredient other than ATG as the
primary reducing agent, such as cysteamine or mercaptamine. (Still damaging )
low-pH waves - Answer -✔✔Perms that use sulfates, sulfites, and bisulfites as an
alternative to ammonium thioglycolate (atg) they have a low pH. Weak don't provide
strong curl
hair density - Answer -✔✔The number of individual hair strands on 1 square inch of
scalp.
hair porosity - Answer -✔✔The ability of the hair to absorb moisture
Hair elasticity - Answer -✔✔The ability of the hair to stretch and return to its original
length
Low porosity - Answer -✔✔When the cuticle is tight and the hair is resistant, it is difficult
for moisture or chemicals to penetrate. What term describes this condition?
High porosity - Answer -✔✔When the cuticle is lifted and the hair is overly porous and
takes color quickly the hair would be said to have
Average porosity - Answer -✔✔The cuticle is slightly raised. The hair is normal and
processes in an average amount of time. (Normal)
Curl rearranger - Answer -✔✔reduces peptide bonds so hair can relax and become
straight; thio-based product (Thio based) (atg)
Curl booster - Answer -✔✔assists hair to assume new shape of rod when wrapping hair
in perm rods; milder form of thio
curl activator - Answer -✔✔Helps new curl configurations retain their shape and
provides moisture; applied frequently after every shampoo
Instant Moisturizer - Answer -✔✔Helps replace natural moisture and oils lost during
chemical processes
